Lowering springs on stock shocks? 1 inch?
Hi all. Looking to finally lower my 09 Yaris Sedan. But I only want to go down about 1 inch, or 25.5mm. Will this be a problem on stock shocks? I don't know how low you can actually go using stock shocks/struts. Well the front 2 are KYB brand replacements, but they're meant to be like stock according to KYB. Lastly, which springs would you use for this task?

Best bet is probably TRD or Eibach springs.

Not gonna harm the shocks or the ride any? I was trying to make sure I avoid messing up the shocks/struts.

I have Tanabe DF210 springs on my 2010 sedan. It gives about a 2 inch drop, which is ok except on some speed bumps in parking lots, and even then I'm ok as long as I go slow.
The NF210 is about 1-1.5 inch drop and rides a little better so they say. Mine is slightly stiffer than stock,but not bad at all. I love them!! Oh and I'm on stock 185/65-15 tires |

I lowered my 07 Sedan at 130k miles. Dropped it 2” on stock struts with Tein S springs. I’m at 212k miles now with no issues whatsoever. DROP IT!!!

TRD or Eibach Prokits will work well with stock shocks. I wouldn't forsee any abnormal wear.

All this does is change the height, right? Do I need to get an alignment afterwards? Have toe/camber adjusted? Again trying to do only the 1 inch.

Any lowering spring will alter the ride quality as they're stiffer springs compared to the OEM springs. Also, any lowering springs will reduce the lifespan of the dampers (shocks). So if your car already has some higher mileage to them, you'll have to pull out the suspension twice (once for installing the springs, and another to replace the dampers when they blow). Any adjustment to the ride height will require an alignment afterwards. Only the front of the Yaris is adjustable. The rear are not unless you use shims. If all you're looking for is an inch drop and you have higher miles on the car (means most likely the dampers are nearing the end of their life), I would suggest getting some basic coilovers like the Tein Basis Z. They're basic coilovers in that they don't have dampening adjustment, but at least the dampers are valved/paired correctly for the spring rate. And you can dial in just how much lowering you want (within the range it provides, which is a little under an inch min to a little under 2 inches max). |

Additionally, I prefer the ride quality after lowering with Tein S. Tech springs than when running stock springs. The Tein's offer a progressive spring rate so it's very nice around town and then sits down under heaving turning. I agree that the Tein Basic's are a good option, but if someone is looking at the budget and has functioning factory shocks/struts, I wouldn't be that concerned about lowering with springs and keeping the OEM shocks/struts for a while. Just my 2 cents. |

That's why I also mentioned about having higher miles since buying springs and then having to buy dampers may end up costing close to those Tein Basis Z coilovers, especially if labor is being paid twice to remove the suspension. If it's on the lower mileage side, like me with Dory, I'd just throw on springs, granted I already had the springs laying around. lol. With that said, with a little under 40k miles since putting the springs on, I believe my rear dampers are going out on Dory. Once they do blow, I'll get a set of Tein Flex Z and give the S.Tech's away. |

For a mere 1" drop, just swap in the new springs. No real need to worry about dampers, shims, camber, toe, etc.

Thanks all! I'll post pics when I'm done. I've inherited this car as a new work car. Yaris is now actually mine full time. So I'm gonna mod it to my liking.
That said, what headlights are high quality enough to replace the oem ones? The car is that black metallic color, so dark colored headlights wouldn't be unwelcome. Just don't want to end up with some cheap junk. |
